Abstract:
The asymmetric unit of the title compound, [Ru(C(15)H(11)N(3))(2)](ClO(4))(2)·0.5H(2)O, contains one ruthenium-terpiridine complex cation, two perchlorate anions and one half-mol-ecule of water. Face-to-face and face-to-edge π-stacking inter-actions between terpyridine units [centroid-centroid distances = 3.793 (2) and 3.801 (2) Å] stabilize the crystal lattice The partially occupied water mol-ecule inter-acts with two perchlorate ions via O-H⋯O hydrogen bonds. In the crystal lattice, the complex cations, perchlorate ion-water pairs and the second perchlorate anions are arranged into columns along b direction.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
